Extreme ExtremeSwitching VSP 4900 Switches - Refurbished, Used, and New
Extreme ExtremeSwitching VSP 4900 switches are fabric edge switches for the campus access and distribution layers, running VOSS with Fabric Connect. They put 1G PoE+ or multigigabit PoE ports on the front for phones, cameras and Wi-Fi 6 access points, 10G SFP+ uplinks on the back, and a slot for a VIM5 Versatile Interface Module that adds 10G or 25G uplinks. Power supplies are modular and sold separately, so you can choose the wattage your PoE load needs. NetworkTigers sells VSP 4900 switches, VIM5 modules and power supplies refurbished, used and new, and every unit is tested before it ships so it works when it arrives.

Which VSP 4900 do I need?
Pick the access ports first. The VSP4900-48P is the standard closet switch: 48 PoE+ ports at 1G for desks, phones and cameras. The VSP4900-12MXU-12XE is the Wi-Fi 6 and small aggregation switch: its 12 multigigabit PoE ports feed access points that need more than 1G, and its 12 SFP+ ports collect 10G fiber from other closets or servers. Next pick the uplinks. The fixed SFP+ ports handle 10G; add a VIM5-4X for four more 10G ports or a VIM5-2Y for two 25G ports to a VSP 7400 or core. The VIM5 modules fit any VSP 4900 model, so you can buy the switch and the module separately. Finally size the power: each switch takes up to two supplies, the 715W 10951 covers the switch and a modest PoE load, and the 1100W 10941 is the one to choose when most ports will draw PoE+ at once. Tell us your PoE device count and we will confirm the supply.
Frequently asked questions
Can a VSP 4900 join a fabric built on older VSP 4000 or VSP 7000 switches?
Yes. The VSP 4900 runs VOSS and Fabric Connect, the same SPB-based fabric as the earlier VSP lines, so it can be added as an edge node to an existing fabric and provisioned with the same services and I-SIDs.
Do I have to run Fabric Connect to use a VSP 4900?
No. It works as a conventional Layer 2 and Layer 3 switch with VLANs, routing and link aggregation. Fabric Connect is there when you want it, and the switch can be moved into a fabric later without a hardware change.
